This tidbit of information took me a ridiculous amount of time to find. The email form in AT&T's account dashboard is completely non-operational for me, and the phone agents weren't able to resolve my issue. Trying to find a direct support email address was tough, but it does exist. If, for any reason, you ever need to directly email AT&T Customer Care, you can do so at ATTCustomerCare@att.com. You can also try tweeting at them.
